Clean Rapid Transfer Port (CRTP)

Safe. Clean. Flexible.

The CRTP is the cleanest and most flexible transfer system on the market.

CRL designed the CRTP as a transfer solution for life sciences applications where cleanability and cleanliness are critical. The CRTP utilizes the same Double Door Transfer System technology as our previous generation RTPs, but introduces new features for ease of use while offering more flexibility.

The CRTP design includes a new handle which utilizes minimal handle rotation to break the seal on the beta container, reducing operator effort for safer handling. It also features a streamlined interlock system with interchangeable beta mounts that can be replaced without breaking containment. The design has also been improved to eliminate exposed fasteners and incorporates a smoother surface for easier cleaning.

Available standard sizes (mm): 105 | 190 | 270 | 350

Flexible Door Options

The CRTP is available in a variety of sizes and configurations to meet the most demanding transfer applications. Door configurations are largely application dependent, and to meet these needs CRL has several options available to provide even more flexibility.

Doors are available in Stainless Steel, Polypropylene, and Liquid Transfer.

Door Option SS

Stainless Steel Door (SS)
(Typically used in strong chemical/radiation or some aseptic applications)

Door Option PP

Polypropylene Door (PP)
(Typically used in pharma, chemical, and nuclear applications)

Door Option LT

Liquid Transfer Door (LT)
(Typically used in filling line and fluid transfer applications)

Interlock System

The CRL Rapid Transfer Port (RTP) features optional mechanical interlocks that prevent the improper operation of the transfer port which can compromise the containment and sterility of the barrier/isolator.

The interlocks are incorporated into the Alpha flange and interface with the alpha port door handle to prevent the following:

  • The Alpha port door from being opened when a Beta flange has not been docked.
  • The Beta flange from being removed from the Alpha flange when the Alpha port door is open.

Beta Mount Inserts

The CRTP’s interchangeable beta mount inserts can be easily replaced without breaking containment. They are available in 3-bayonet or 4-bayonet insert options, allowing never before seen versatility.
